Roughly 160 people are dead and hundreds more — including dozens of international tourists — are missing after flash floods hit a region on the mountainous border of Nepal and Tibet on Wednesday. Devastating footage posted to social media shows people fleeing a wall of water that washed away buildings and vehicles.
Initial analysis of satellite imagery and reports from the Nepalese government indicate that the flooding was likely triggered by a landslide caused after a piece of a glacier fell hundreds of feet.
As the region warms, its ice is becoming increasingly unstable, raising the risk of catastrophic flooding.
“The glaciers over there are definitely in retreat,” said Joseph Shea, an associate professor of geography at the University of Northern British Columbia. “There’s a lot of glacier mass up there, but we’re seeing thinning, we’re seeing retreating.”
